Yes I did try visiting the link. It was helpful but did answer all my questions. Thanks for the picture helps me understand the top line better. Also I know that the anal shouldn't extend past the bottom of the cadual, correct? But then also something about the slope of it. Does this mean the front and back of the anal fin should be equal lenght?

depends on tail types, have a look at bettysplendens.com again..find "the tailtype" articles, for example..The Halfmoon..that should explain and give you better examples :)

I'm not really sure yet. The father did have some extensive branching but not too bad. That's why he was bred. The last ones fins were normal before I bought him. The seller said they just grew like that. But I believe it is just damage as some fins webbing is like that but then parts are different. I think it will grow back
